The whole bible assumes a flat earth. Honestly, google it and you'll come up with a treasure trove of flat earth arguments made from the bible. I'm not going to make you a list, but here's a short video made by biblical scholar explaining how the ancient israelites viewed cosmology.
And one much more in depth:
And here's someone on Youtube who builds a case for a flat earth from 75 bible verses.
@garthfreeman, I was born into Protestantism and later in my life became a Baptist. I did this Bibleschool training and I believe what they taught. I am not big into science, I concern myself to be ready when Jesus comes again. You are free to interpret the Bible and I am free to interpret the Bible. I believe like a child. I looked at your blog and will follow you, if I am not mistaken we are both children of our Heavenly Father. May you be blessed!
Thanks for your kind words. It's exactly this kind of grace towards each other that I am arguing for. I really dislike all the name-calling and labeling between brothers and sisters when relatively minor disagreements occur. God bless you as well, and have a great day!
Thank you @garthfreeman. :-)
